For example, the data may be data of a type supported by thewearable electronic device 101, for example, image data or text data.

In operation 702, the processor 120 according to an embodiment mayidentify whether the wearable electronic device 101 is worn. Theprocessor 120 may detect whether a user is wearing the wearableelectronic device 101. For example, when receiving data periodically orfrom the host device, the processor 120 may detect whether the wearableelectronic device 101 is worn using a first sensor (e.g., a first sensor341 of FIG. 3). When the user is wearing the wearable electronic device101 (YES in operation 702), the processor 120 may proceed to operation703. When the user is not wearing the wearable electronic device 101 (NOin operation 702), the processor 120 may proceed to operation 704.

In operation 703, the processor 120 according to an embodiment maydisplay screens in an inner direction (e.g., a first direction D1 ofFIG. 2). When the user is wearing the wearable electronic device 101,the processor 120 may determine that the wearable electronic device 101is used. The processor 120 may display the screens in the innerdirection (e.g., the first direction D1 of FIG. 2) which is a directionwhere the user exists. The processor 120 may control the display module160 to display the screens in the inner direction (e.g., the firstdirection D1 of FIG. 2).

In operation 704, the processor 120 according to an embodiment mayidentify a direction where the wearable electronic device 101 is placed.When the user is not wearing the wearable electronic device 101, theprocessor 120 may determine a direction where the wearable electronicdevice 101 is placed using a second sensor (e.g., a second sensor 342 ofFIG. 3). The processor 120 may set directions of the screens output ondisplay areas 221 and 222 by the display module 160 depending on thedirection the wearable electronic device 101 is placed.

In an embodiment of the disclosure, when the wearable electronic device101 is in a first state where it is placed in the same direction as astate where the user is wearing the wearable electronic device 101, theprocessor 120 may maintain vertical directions of the output screens.When the wearable electronic device 101 is in a second state where it isplaced in an inverted direction as compared with the state where theuser is wearing the wearable electronic device 101, the processor 120may invert the vertical directions of the output screens. When theprocessor 120 is in the second state while performing operation 704 ofdetecting the direction where the wearable electronic device 101 isplaced, the processor 120 may invert the vertical direction of theoutput screen. However, the processor 120 is not limited thereto, whichmay invert the vertical direction of the output screen, when theprocessor 120 is in the second state while performing operation 708 or710 of displaying the screen after proceeding with operation 704.

In operation 705, the processor 120 according to an embodiment mayidentify whether a frame (e.g., a first housing portion 210 and/or athird housing portion 230 of FIG. 2) of the wearable electronic device101 is folded. The processor 120 may determine that the user identifiesscreens in an outer direction (e.g., a second direction D2 of FIG. 2)when the frame of the wearable electronic device 101 is folded in astate where the user is not wearing the wearable electronic device 101.The processor 120 may determine that the user identifies the screens inan inner direction (e.g., a first direction D1 of FIG. 2) or the outerdirection (e.g., the second direction D2 of FIG. 2) of the wearableelectronic device 101 when the frame of the wearable electronic device101 is unfolded in the state where the user is not wearing the wearableelectronic device 101. When the frame of the wearable electronic device101 is folded (YES in operation 705), the processor 120 may proceed tooperation 706. When the frame of the wearable electronic device 101 isunfolded (NO in operation 705), the processor 120 may proceed tooperation 709.

In operation 706, the processor 120 according to an embodiment mayidentify a position of the user. When receiving data in the state wherethe frame of the wearable electronic device 101 is folded, the processor120 may identify the position of the user with respect to the wearableelectronic device 101. The processor 120 may identify a distance betweenthe wearable electronic device 101 and the user using first cameras(e.g., first cameras 311 and 312 of FIG. 3) and a third camera (e.g., athird camera 330 of FIG. 3). The processor 120 may identify whether theface of the user is located at any of upper, lower, right, and leftsides with respect to the wearable electronic device 101 using the firstcameras 311 and 312 and the third camera 330.

In operation 707, the processor 120 according to an embodiment maychange output areas and/or brightnesses of the screens. The processor120 may adjust the output areas of the screens depending on the distancebetween the wearable electronic device 101 and the user. The processor120 may adjust the brightnesses of the screens depending on the distancebetween the wearable electronic device 101 and the user.

In operation 708, the processor 120 according to an embodiment maydisplay the screens in an outer direction (e.g., a second direction D2of FIG. 2). When the frame of the wearable electronic device 101 isfolded in a state where the user is not wearing the wearable electronicdevice 101, the processor 120 may set output areas and/or brightnessesof the screens depending on the position of the user and may control thedisplay module 160 to display the screens in the outer direction (e.g.,the second direction D2 of FIG. 2).

In an embodiment of the disclosure, the processor 120 may be configuredto reverse and display the screens when displaying the screens in theouter direction (e.g., the second direction D2 of FIG. 2). The processor120 may control the display module 160 to reverse and display thescreens when displaying the screens in the outer direction (e.g., thesecond direction D2 of FIG. 2). When the user identifies the screensdisplayed in the outer direction (e.g., the second direction D2 of FIG.2), the screens may be reversed as compared with identifying the screensdisplayed in the inner direction (e.g., the first direction D1 of FIG.2). When reversing and displaying the screens when displaying thescreens in the outer direction (e.g., the second direction D2 of FIG.2), the user may see the same screens as screens internally identified.

In an embodiment of the disclosure, when the user is not located in theouter direction (e.g., the second direction D2 of FIG. 2) of thewearable electronic device 101, the processor 120 may control thedisplay module 160 to output the screens in the outer direction (e.g.,the second direction D2 of FIG. 2) without changing a separate screensetting.

In an embodiment of the disclosure, for the wearable electronic device101 in form of a head mounted display (HMD) rather than in the form ofglasses, the operation where the frame is folded may be omitted. Theprocessor 120 may determine whether the wearable electronic device 101in the form of the HMD is worn. When the user is not wearing thewearable electronic device 101 in the form of the HMD, the processor 120may omit operation 705 and may perform operations 704, 706, 707, and708. The processor 120 may control the display module 160 such that thewearable electronic device 101 in the form of the HMD displays screensin the outer direction (e.g., the second direction D2 of FIG. 2).

In operation 709, the processor 120 according to an embodiment mayidentify whether the user is located in the second direction D2 of thewearable electronic device 101. The processor 120 may identify whetherthe user is located in the second direction D2 of the wearableelectronic device 101 using the first cameras 311 and 312 and/or thethird camera (e.g., a third camera 330 of FIG. 3). When the user islocated in the second direction D2 of the wearable electronic device 101(YES in operation 709), the processor 120 may proceed to operation 707.When the user is not located in the second direction D2 of the wearableelectronic device 101 (NO in operation 709), the processor 120 mayproceed to operation 710.

In operation 710, the processor 120 according to an embodiment mayrespectively display the screens in the inner direction (e.g., the firstdirection D1 of FIG. 2) and the outer direction (e.g., the seconddirection D2 of FIG. 2). When it is unable to identify whether the useris located in any of the inside and/or the outside of the wearableelectronic device 101, the processor 120 may control the display module160 to respectively display the screens in the inner direction (e.g.,the first direction D1 of FIG. 2) and the outer direction (e.g., thesecond direction D2 of FIG. 2). The user may identify the screens in anyof the inner direction (e.g., the first direction D1 of FIG. 2) and theouter direction (e.g., the second direction D2 of FIG. 2). When the useris not located in the outer direction (e.g., the second direction D2 ofFIG. 2) of the wearable electronic device 101, in operation 710, theprocessor 120 according to another embodiment may control the displaymodule 160 to display the screens in only the inner direction (e.g., thefirst direction D1 of FIG. 2). When the user is not located in the outerdirection (e.g., the second direction D2 of FIG. 2) of the wearableelectronic device 101, in operation 710, the processor 120 according toanother embodiment may control the display module 160 not to display thescreens.

According to an embodiment of the disclosure, in performing operation708 or operation 710, when it is determined that the user is not locatedin the outer direction (e.g., the second direction D2 of FIG. 2) of thewearable electronic device 101 or within a specified angle during aspecified time using the first cameras 311 and 312 and the third camera330, the processor 120 may control the display module 160 not to displaythe screens.

FIG. 8 is a drawing 800 illustrating screens displayed on display areas221 and 222 by a display (e.g., a display module 160 of FIG. 3) of awearable electronic device 101 according to an embodiment of thedisclosure.

In an embodiment of the disclosure, a processor (e.g., a processor 120of FIG. 3) of the wearable electronic device 101 may determine adirection where the wearable electronic device 101 is placed using asecond sensor (e.g., a second sensor 342 of FIG. 3). The second sensor342 may be an inertial measurement unit (IMU) sensor and/or a magneticsensor.

In an embodiment of the disclosure, the processor (e.g., the processor120 of FIG. 3) of the wearable electronic device 101 may identify aposition of a user using first cameras (e.g., first cameras 311 and 312of FIG. 3) and a third camera (e.g., a third camera 330 of FIG. 3). Forexample, the wearable electronic device 101 may identify that the useris located in a second direction (e.g., a second direction D2) of thewearable electronic device 101.

In an embodiment of the disclosure, the processor 120 may set directionsof screens output on the display module 160 based on a direction thewearable electronic device 101 is placed. The processor 120 maydetermine the direction where the wearable electronic device 101 isplaced with respect to the ground parallel to a landscape orientation.

Referring to FIG. 8, when the wearable electronic device 101 is in asecond state 820 with respect to the ground, the processor 120 maycontrol the display module 160 to invert and display screens. When thewearable electronic device 101 is in a first state 810, the processor120 may control such that the display module 160 reverses and outputsoriginal screens on display areas 221 and 222. When the wearableelectronic device 101 is in the second state, the processor 120 maycontrol such that the display module 160 reverses and inverts theoriginal screens and outputs the reversed and inverted screens on thedisplay areas 221 and 222. When the processor 120 controls the screensoutput on the display module 160 with regard to the direction where thewearable electronic device 101 is placed, the user may easily identifythe screens irrespective of the direction where the wearable electronicdevice 101 is placed.

FIG. 9 is a drawing 900 illustrating an appearance in which a useridentifies a wearable electronic device 101 according to an embodimentof the disclosure.

Referring to FIG. 9, when the user is wearing the wearable electronicdevice 101, an eye 910 of the user may see a first glass 211 of thewearable electronic device 101 in a field of view (FOV) θ1. For example,the eye 910 of the user and the glass 911 may have a first distance A1.When the user is wearing the wearable electronic device 101, a virtualimage position 930 may be present to be spaced apart from the wearableelectronic device 101 at a third distance A3. The third distance A3 mayvary with a curvature of the first glass 211. For example, the thirddistance A3 may be greater than or equal to about 1 M and be less thanor equal to about 2 M.

In an embodiment of the disclosure, when the user is spaced apart fromthe wearable electronic device 101 in a state where the user is notwearing the wearable electronic device 101, the eye 920 of the user mayhave a second distance A2 from the first glass 211 of the wearableelectronic device 101. When the user is spaced apart from the wearableelectronic device 101 in the state where the user is not wearing thewearable electronic device 101, the eye 920 of the user may see thefirst glass 211 of the wearable electronic device 101 in a second FOVθ2. The second FOV θ2 may be less than the first FOV θ1.

In an embodiment of the disclosure, when a position of the view the useris looking at changes, a shape of a virtual image capable of beingviewed at the virtual image position 930 may change. When the user isspaced apart from the wearable electronic device 101 in the state wherethe user is not wearing the wearable electronic device 101, a rangewhere it is able to view a virtual image at the virtual image position930 may be more reduced than when the user is wearing the wearableelectronic device 101.

In an embodiment of the disclosure, when the second distance A2 which isa distance between the wearable electronic device 101 and the user(e.g., a position of the user's gaze) changes, an eye relief positionmay change and an eye box area which is an area capable of showing theuser screens of the display module 160 may change. The eye box area maybe an area where the user may identify all the screens displayed ondisplay areas 221 and 222 by the display module 160.

FIG. 10 is a drawing 1000 illustrating screens displayed on displayareas 221 and 222 by a display (e.g., a display module 160 of FIG. 3) ofa wearable electronic device 101 according to an embodiment of thedisclosure.

In an embodiment of the disclosure, screens of the wearable electronicdevice 101 may configure eye box areas (e.g., a first distance A1 ofFIG. 4) to correspond to when the user is wearing the wearableelectronic device 101.

Referring to FIG. 10, a user 1010 may be spaced apart from the wearableelectronic device 101 in a state where the user 1010 is not wearing thewearable electronic device 101 to identify screens. When the user isspaced apart from the wearable electronic device 101 in the state wherethe user is not wearing the wearable electronic device 101 to identifythe screens, eye box areas showing virtual screens may be reduced. Whenthe distance between the wearable electronic device 101 and the userincreases and the eye box areas are reduced, partial areas of thescreens may be zoomed in to be seen. When the partial areas of thescreens displayed on the display areas 221 and 222 are zoomed in to beseen, at least a portion of content displayed on the screens may fail tobe visually seen to the user.

FIG. 11 is a drawing 1100 illustrating screens displayed on displayareas 221 and 222 by a display (e.g., a display module 160 of FIG. 3) ofa wearable electronic device 101 according to an embodiment of thedisclosure.

Referring to FIG. 11, a user 1110 may verify screens at a positiontilted from the wearable electronic device 101 in a state where the user1110 is not wearing the wearable electronic device 101.

In an embodiment of the disclosure, when the user identifies the screensat the position tilted with respect to an outer direction (e.g., asecond direction D2 of FIG. 2), eye box areas may lean to one corner ofthe display areas 221 and 222. Furthermore, partial areas of the screensmay be zoomed in to be seen. Thus, the screens zoomed in on the cornerportions to which the eye box areas lean may be seen. When the screenszoomed in on the corner portions to which the eye box areas lean areseen, at least a portion of content displayed on the screens may fail tobe visually seen to the user. For example, at least a portion in acorner opposite to the corner to which the eye box areas lean in contentincluded in the screens displayed on display areas 221 and 222 may failto be visually seen to the user.

FIG. 12 is a drawing 1200 illustrating a method for calculating adistance between a wearable electronic device 101 and a user 1210 and aposition of a user according to an embodiment of the disclosure.

Referring to FIG. 12, the user 1210 may be located in a second directionD2 which is an outer direction of the wearable electronic device 101. Aprocessor (e.g., a processor 120 of FIG. 1) of the wearable electronicdevice 101 may calculate a distance between the wearable electronicdevice 101 and the user 1210 using first cameras 311 and 312 and a thirdcamera 330. The processor 120 may calculate a position of the user 1210located in the second direction D2 using the first cameras 311 and 312and the third camera 330.

In an embodiment of the disclosure, the processor 120 may measure afourth distance A4 which is a distance of the user 1210 in the seconddirection D2 from the wearable electronic device 101 using the thirdcamera 330. The processor 120 may measure a fifth distance A5 and asixth distance A6 which are distances of the user 1210 from both ends ofthe wearable electronic device 101 using the first cameras 311 and 312.The processor 120 may calculate a seventh distance A7 and an eighthdistance A8, which are distances where the user 1210 sees display areas221 and 222 of glasses 211 and 212, using the measured fourth distanceA4, fifth distance A5, and sixth distance A6. The processor 120 mayidentify a distance between the wearable electronic device 101 and theuser 1210 using a depth camera and a gesture camera.

In an embodiment of the disclosure, the processor 120 may calculateangles where the user 1210 sees the display areas 221 and 222 of theglasses 211 and 212, using the measured fourth distance A4, fifthdistance A5, and sixth distance A6. The processor 120 may calculate aposition of the user 1210 based on the angles where the user 1210 seesthe display areas 221 and 222 of the glasses 211 and 212. The positionof the user 1210 may include information about whether the face of theuser 1210 is located at any of an upper portion, a lower portion, a leftside, or a right side with respect to the wearable electronic device101. The processor 120 may identify whether the user 1210 gazes at thescreens displayed on the display areas 221 and 222 of the glasses 211and 212 in any direction based on the calculated position of the user1210.

FIG. 13 is a drawing 1300 illustrating screens displayed on displayareas 221 and 222 by a display (e.g., a display module 160 of FIG. 3) ofa wearable electronic device 101 according to an embodiment of thedisclosure.

Referring to FIG. 13, a processor 120 may change output areas of thescreens depending on a calculated distance between the wearableelectronic device 101 and a user 1310. The processor 120 may comparesizes of display areas 221 and 222 based on the distance between thewearable electronic device 101 and the user 1310 as shown in Table 1 tochange sizes of the output areas of the screens.

TABLE 1 Distance between Sizes of output areas of wearable electronicscreens compared with sizes device 101 and user 1310 of display areas221 and 222 20 cm 90% 40 cm 80% 60 cm 70% 80 cm 60%

In an embodiment of the disclosure, the processor 120 may be configuredto display the screens based on the changed output areas. The processor120 may calculate a change in sizes of eye box areas capable of showingthe screens depending on the distance of the user 1310. The processor120 may change the output areas of the screens to correspond to thechanged eye box areas. As the distance between the wearable electronicdevice 101 and the user 1310 increases, when the eye box areas arereduced and when the screens are zoomed in to be seen, the processor 120may change the output areas of the screens to be substantially the sameas the eye box areas. The processor 120 may prevent the user 1310 fromseeing screens cut at edges of the display areas 221 and 222. Theprocessor 120 may change the output areas of the screens such that theuser 1310 identifies intact screens.

In an embodiment of the disclosure, the processor 120 may be configuredto adjust a size of content displayed on the screens depending on thedistance between the wearable electronic device 101 and the user 1310.As the distance between the wearable electronic device 101 and the user1310 increases, the processor 120 may reduce the size of the contentdisplayed on the screens to correspond to a phenomenon in which the eyebox areas of the user are reduced and when the screens are zoomed in tobe seen. Thus, the processor 120 could reduce a phenomenon in whichcontent is cut at edges of the display areas 221 and 222 as the screensare zoomed in to be seen, such that the user 1310 may easily identifythe content displayed on the screens.

In an embodiment of the disclosure, the processor 120 may changebrightnesses of the screens depending on the distance between thewearable electronic device 101 and a user 1310. The processor 120 maychange brightnesses of the screens compared with brightnesses of thescreens when the user 1310 is wearing the wearable electronic device 101based on the distance between the wearable electronic device 101 and theuser 1310.

TABLE 2 Brightnesses of screens compared Distance between withbrightnesses of screens wearable electronic when user 1310 is wearingwearable device 101 and user electronic device 101 20 cm 110% 40 cm 120%60 cm 130% 80 cm 140%

In an embodiment of the disclosure, the processor 120 may be configuredto display the screens based on the changed brightnesses. When thedistance between the wearable electronic device 101 and the user 1310increases, brightnesses of the screens shown to the user 1310 maydecrease. The processor 120 may increase the brightnesses of the screenswith regard to a decrease in brightness detected by the user 1310. Thus,the processor 120 could reduce a phenomenon in which the brightness ofthe screens the user 1310 sees reduce. The processor 120 may adjust thebrightnesses of the screens such that the user 1310 identifies intactscreens.

In an embodiment of the disclosure, the processor 120 may change outputareas of the screens based on the calculated position of the user 1310.The processor 120 may change the output areas of the screens such thatthe screens are viewed in the center without leaning when viewing thescreens at the calculated position of the user 1310.

In an embodiment of the disclosure, the processor 120 may changebrightnesses of the screens based on the calculated position of the user1310. The more distant the calculated position of the user 1310 departsfrom the front of a second direction (e.g., a second direction D2 ofFIG. 2) of the wearable electronic device 101, the brighter theprocessor 120 may make the screens. The processor 120 may adjust thebrightnesses of the screens such that it is easy for the user 1310 toidentify the screens at a tilted angle.

FIG. 14 is a drawing 1400 illustrating screens displayed on displayareas 221 and 222 by a wearable electronic device 101, when a user isnot wearing a wearable electronic device 101, according to an embodimentof the disclosure.

Referring to FIG. 14, when the user is not wearing the wearableelectronic device 101, the processor 120 may control a display (e.g., adisplay module 160 of FIG. 3) to output screens including a message(e.g., Hello. How are you?) identifying where the user is.

In an embodiment of the disclosure, when the position of the user is notidentified, the processor 120 may respectively output screens in a firstdirection D1 which is an inner direction and a second direction (e.g., asecond direction D2 of FIG. 2) which is an outer direction. Theprocessor 120 may output a screen of a first display area 221 betweendisplay areas 221 and 222 in the first direction D1 and may output ascreen of the second display area 222 in the second direction D2. Thus,the user may identify the screens in a direction where the user iscurrently located between the first direction D1 or the second directionD2. For example, the screens displayed on the first display area 221 andthe second display area 222 of FIG. 14 may correspond to an operation ofrespectively displaying the screens in the inner direction (e.g., thefirst direction D1 of FIG. 2) and the outer direction (e.g., the seconddirection D2 of FIG. 2) in operation 710 of FIG. 7.

The lens module 1710 may be disposed at aposition corresponding to positions of screens displayed on displayareas 221 and 222 by a display (e.g., a display module 160 of FIG. 3).For example, when the wearable electronic device 101 is received in thereceiving part 1520, the lens module 1710 may be located substantiallyparallel to and overlapped with the display areas (e.g., the displayareas 221 and 222 of FIG. 3).

FIG. 20 is a drawing 2000 illustrating a case 1510 including lensmodules 1711 and 1712 (e.g., a lens module 1710 of FIG. 17 and/or FIG.18) according to an embodiment of the disclosure.

Referring to FIG. 20, the case 1510 may further include a shieldingmember 2010 for selectively covering or opening the lens module 1710.For example, the lens modules 1711 and 1712 may be plural (e.g., 2) innumber to correspond to glasses (e.g., glasses 211 and 212 of FIG. 2) ofthe wearable electronic device (e.g., the wearable electronic device 101of FIG. 2). The shielding member 2010 may be an opaque member disposedon an inner surface of the lens modules 1711 and 1712. For example, theshielding member 2010 may be including one shielding member to includethe lens modules 1711 and 1712 as shown in FIG. 20 or may be including aplurality of shielding members to correspond respectively to the lensmodules 1711 and 1712 as shown in FIG. 21. The shielding member 2010 mayautomatically and/or manually hide inner surfaces of the lens modules1711 and 1712. When hiding the inner surface of the lens module 1710,the shielding member 2010 may hide screens displayed by the wearableelectronic device (e.g., the wearable electronic device 101 of FIG. 2).The shielding member 2010 may be automatically and/or manually folded tobe spaced apart from the inner surfaces of the lens modules 1711 and1712 and be located on an inner surface of the case 1510 except for asurface where the lens modules 1711 and 1712 are arranged. When theshielding member 2010 is folded to be located on the inner surface ofthe case 1510 except for the surface where the lens modules 1711 and1712 are arranged, a user may identify screens displayed by the wearableelectronic device (e.g., the wearable electronic device 101 of FIG. 2)by means of the lens modules 1711 and 1712.

In an embodiment of the disclosure, second communication circuitry(e.g., second communication circuitry 1620 of FIG. 16) may receive anactivation signal, while a display (e.g., a display module 160 of FIG.3) displays screens on the display areas 221 and 222, from firstcommunication circuitry (e.g., first communication circuitry 1610 ofFIG. 16). When the second communication circuitry 1620 receives theactivation signal, a controller (e.g., a controller 1630 of FIG. 16) ofthe case 1510 may determine that the display module 160 displays thescreens on the display areas 221 and 222.

In an embodiment of the disclosure, the shielding member 2010 mayselectively cover or open the lens modules 1711 and 1712 based on theactivation signal. When the second communication circuitry 1620 receivesthe activation signal, the controller 1630 may control the shieldingmember 2010 to open the lens modules 1711 and 1712. When the secondcommunication circuitry 1620 does not receive the activation signal, thecontroller 1630 may control the shielding member 2010 to cover the lensmodules 1711 and 1712. When the shielding member 2010 opens the lensmodules 1711 and 1712 while receiving the activation signal, the usercould identify the screens displayed on the display areas 221 and 222 bythe lens modules 1711 and 1712. When the shielding member 2010 coversthe lens modules 1711 and 1712 while receiving the activation signal,the wearable electronic device (e.g., the wearable electronic device 101of FIG. 19) which is in an inactive state may be kept in a state whereit is not seen from the outside of the case 1510.
